Have you been using dry shampoo wrong? This hack beats grease for longer

After applying the spray, she flips her head upside down and shakes out her hair by the roots to use the spray as a “root volumizer.”

While viewers championed her easy hair hack, others voiced concerns regarding over-using dry shampoo on the hair and scalp, a longstanding point of contention among beauty lovers.

Despite its name, dry shampoo doesn’t cleanse the hair, and relying on it between washes may lead consumers to under-wash their scalp and strands.

While sprinkling on some of the powdered product is fine post-workout or when you’re in a pinch, experts advise against substituting it for a true shampoo and condition.

“Dry shampoos should not be used as a regular replacement for real shampoo, as they simply do not clean the scalp; they do not remove oils, dead skin cells, pollution, sweat or other products,” Anabel Kingsley, the president and head trichologist of the haircare brand Philip Kingsley, told Byrdie.

“Remember, your scalp is skin and needs similar TLC to be healthy — and hair grows its best from a healthy scalp.”

Experts have long debated the perfect time to forego washes, with recommendations ranging from once a week to every other day depending on hair type and lifestyle.

 “If you only wash your hair once or twice a week, you should double cleanse (as in shampoo twice) and then condition as usual,” Kingsley told Byrdie.

“For infrequent hair washers, I also recommend using a daily anti-microbial scalp toner and a weekly exfoliating scalp mask to give your scalp a little helping hand.”
